Definitions

  • This invention relates to a vehicle inner panel, for example, a door inner panel.
  • a door inner panel which has fabric over its entire surface or a considerable portion thereof, and sometimes that fabric requires a sub-panel of matching or contrasting fabric, say for example around the armrest area.
  • the contrasting or matching fabric may have a different texture for improved resistance to wear.
  • a moulded foam comprises a surface layer of elastomeric thin film, an intermediate reinforcing layer of elastic film, and a core layer.
  • This invention seeks to provide a method which will be economical and which will not involve excessive labour in providing a panel of padded fabric for the facing surface of a vehicle inner panel, for example a door inner panel, and be capable of providing a sub-panel of different fabric, at least partly surrounded by a padded fabric panel.
  • a panel of padded fabric for the facing surface of a vehicle inner panel, for example a door inner panel
  • a sub-panel of different fabric at least partly surrounded by a padded fabric panel.
  • This invention provides a method of producing a vehicle inner panel with a padded fabric surface, and includes firstly moulding a substrate of polymeric material, suitably polyurethane, attaching the substrate to one die of a two part die set, stretching a fabric sheet on a stretch frame, interposing the stretched fabric sheet between the other die of the die set and the substrate, injecting foam forming polyurethane through the substrate and allowing it to foam while the dies are closed, opening the dies, removing the assembly, and trimming the fabric.
  • a substrate of polymeric material suitably polyurethane
  • the method includes firstly moulding a substrate to have a groove defining the periphery of a fabric sub-panel, cementing the sub-panel to the face of the substrate and incorporating the peripheral edge of the sub-panel into the groove but allowing it to overlap the groove area if required, positioning the substrate with its sub-panel cemented thereto into one portion of a die, stretching the remaining fabric facing panel across a stretch frame and incorporating into the die, closing the die to force portion of the main panel fabric also into the groove by projection means on the die, and injecting the ingredients of a foam forming polyurethane through the substrate and into the space between the main fabric panel and the substrate to provide a soft padding.
  • removal of the overlying portion of the main panel from the sub-panel of fabric may be simply achieved by cutting the fabric of the main panel where it has entered the groove.
  • a door inner panel 10 is provided with a facing fabric sub-panel 11 capable of accoepting heavy wear conditions (at the locality of the armrests), and a facing fabric main panel 12, the sub-panel and main panel both being formed of fabric material and the main panel 12 preferably being of a velour material.
  • the invention is in no way limited to such material, but it is desirable that at least the main panel 12 should be of a fabric capable of stretch in two directions.
  • the first stage of production (Stage A, Fig. 2) is to separately form a substrate 13 of cross linked polymeric material, in this embodiment polyurethane, to provide a firm backing for the fabric panels 11 and 12.
  • the die parts have a mating groove 18 and blade 19 so that substrate 13 is formed with a groove 20 as seen in Stages C and D of Fig. 2.
  • substrate 13 is punched to provide key-holes by which it can be located in a subsequent die, and also foam injection apertures. These are described below. It may also be trimmed.
  • Stage C substrate 13 is inverted, a layer of soft polyurethane padding 25 is cemented over an arm rest portion 26 of the substrate, the fabric sub-panel 11 is cemented to the then upper surface of substrate 13, and the edges are depressed into the groove 20 by blades 27 of a small inserting tool 28.
  • the sub-panel 11 can be a single sheet of cloth, or a laminate as shown, having an intermediate layer 29 of foam polymeric material to provide a "soft" feel.
  • the aperture is chosen to be at a locality where an aperture is otherwise required (for example, a door handle aperture).
  • a sheet of velour having a backing film of polyurethane, and which is to become the main fabric panel 12, is stretched over a peripheral frame 32 having a touch and hold upper surface 33 (or a series of retaining pins projecting from that upper surface), which retains the fabric edges. Vacuum may be applied through apertures 33 to draw the main fabric panel downwardly over the substrate. It is important that the main panel 12 should be stretchable, and localised initial stretch may be imparted as at 34 if necessary.
  • the upper die part 37 of a second die set 38 has projecting pins 39 which penetrate the key-holes (not shown) to carry the initial sub-assembly, and is closed against the lower die part 40.
  • Projecting blade 41 forces the velour of the main fabric panel 12 up into the groove 20, so that the velour then completely overlies the sub-panel 11.
  • the ingredients of foamable polyurethane is injected through the injection nozzles 42 and injection apertures 43 in the substrate 13 while the dies are closed and this is allowed to foam and cure between substrate 13 and fabric panel 12, while at the same time the glue between the fabric sub-panel 11 and substrate 13 also cures.
  • the assembly is removed from the die and the overlying part 45 of the main fabric panel 12 is cut away from the underlying sub-panel 11 so as to expose it, by means of a hand operation, cutting the main fabric panel 12 in groove 20 with a knife.
  • This operation is very quick because the knife is guided in its movement through the groove 20 by the material which is contained therein.
  • Peripheral edges 46 of panel 12 are returned over the back face of substrate 13, to which they are cemented.
  • the polyurethane foam 47 forms a padding which fills the void between the main fabric panel 12 and the substrate 13, and applies a tension to the main fabric panel 12.
  • the panel may be subjected to a punching operation, for further holes required to house ashtrays, handles, locks and other accessories.
  • the resultant panel is found to have a very pleasing appearance, and is inexpensive to produce.
  • Fig. 3 shows a minor modification wherein the padding 25 is replaced by foam 47 injected through a further nozzle 42 during the injection stage (Stage D).
  • the sub-panel may be retained in position by vacuum applied through apertures 33 in the upper die part 37.
  • the modification required is only small for producing a facing which partly comprises a coloured facing film. Either the entire area is sprayed or only that portion which will be exposed, and the fabric is applied in the same way and its edge is trimmed with a knife or cutting tool.
